  In the waterproof case 1 of the conventional example, when a portable electronic device having a mobile phone function such as iPhone (registered trademark) is accommodated, the waterproof case 1 has high sealing performance. There is a problem that the microphone (speaker) cannot sufficiently pick up the user's voice.

  Even if it is devised so that the user's voice can be picked up by forming the thickness of the vicinity of the microphone of the waterproof case 1 thin, the voice is trapped inside the waterproof case 1, and the microphone picks up again. There is also a problem that a howling phenomenon occurs.

  Therefore, in the waterproof case 1 in the conventional example, the microphone (speaker) of the portable electronic device can pick up the user's voice, and the howling phenomenon at that time can be prevented. Has a problem that must be.

  The gist of the present invention for solving the problems of the conventional example is a waterproof case for storing a portable electronic device having at least a mobile phone function, and the waterproof case includes a back surface and both side surfaces of the portable electronic device. A back side case member made of silicone resin that covers the upper surface and the lower surface, and a front side case member made of synthetic resin that covers the back side case member and covers the front of the portable electronic device, the back side The lower part of the case member is provided with a thin film part in which the silicone resin is formed in a thin film at a position corresponding to the microphone part and the speaker part provided on the lower surface of the portable electronic device. The protrusions for preventing the howling by suppressing the above are integrally formed.

A lower portion of the front case member has a hole formed at a position corresponding to the thin film portion;
Is included.

According to the waterproof case according to the present invention, the microphone (speaker) of the portable electronic device makes the user's voice clearer by providing a thin film portion made of silicone resin at the lower part of the back case member. Can be picked up.
In addition, since the thin film part is integrally formed with a protrusion for suppressing vibration and preventing howling, the reverberation of the vibration of the thin film part due to sound is suppressed, so that sound is trapped inside the waterproof case. As a result, various excellent effects of preventing the howling phenomenon can be obtained.

  In addition, the lower portion of the front case member is formed with a hole at a position corresponding to the thin film portion, so that the thin film portion of the rear case member is not obstructed by the lower portion of the front case member. As a result, the microphone (speaker) of the portable electronic device can sufficiently pick up the user's voice.

It is a perspective view of the back side of waterproof case 21 concerning the present invention. It is explanatory drawing which isolate | separated and showed the waterproof case 21 which concerns on this invention to the back side case member 23, the portable electronic device 22, and the front side case member 24. FIG. 3 is a perspective view of a portable electronic device 22. FIG. (A) It is a bottom view of the waterproof case 21 which concerns on this invention. (B) It is the bottom view which isolate | separated and showed the waterproof case 21 in the back side case member 23 and the front side case member 24. FIG. (C) It is the front view which expanded and showed the thin film part 35. FIG. It is the DD sectional view taken on the line of FIG. It is a longitudinal cross-sectional view which expands and shows the principal part of the waterproof case 1 which concerns on a prior art example.

  Next, embodiments of the present invention will be described with reference to the drawings. 1 to 3, reference numeral 21 denotes a waterproof case. The waterproof case 21 includes a back side case member 23 that covers the back surface 22a, both side surfaces 22b, the upper surface 22c, and the lower surface 22d of the portable electronic device 22. The front-side case member 24 covers the back-side case member 23 and covers the front surface 22e of the portable electronic device 22.

  The waterproof case 21 is a case for watertightly storing the portable electronic device 22 having a liquid crystal touch panel 25 and having a mobile phone function like a smartphone (high function mobile phone). The illustrated portable electronic device 22 is formed in a thin casing shape such as iPhone (registered trademark), for example.

  The back side case member 23 is formed of a flexible silicone resin, and a transparent resin plate 27 is attached at a position corresponding to the camera lens 26 provided on the back surface 22 a of the portable electronic device 22. Therefore, it is possible to take a picture with the portable electronic device 22 stored.

  An upper portion 42 of the back side case member 23 is formed with a sleeve switch protrusion 29 for ON / OFF operation of the sleeve switch 28 provided on the upper surface 22 c of the portable electronic device 22.

  One side portion 30 of the back side case member 23 is formed with a volume adjustment protrusion 32 for operating the volume adjustment button 31 provided on the side surface 22 b of the portable electronic device 22.

  As shown in FIGS. 5A, 5B, and 5C, the lower portion 33 of the back side case member 23 includes a microphone part (speaking mouth) 34a and a speaker part 34b (see FIG. 4) on the lower surface 22d of the portable electronic device 22. A thin film portion 35 in which a silicone resin is formed in a thin film shape is provided at a position corresponding to the reference). The presence of the thin film portion 35 causes the user's voice to vibrate and propagate, so that the microphone 34a of the portable electronic device 22 can clearly pick up the user's voice.

  In addition, as an example of the dimension of the thin film part 35, the dimension of a longitudinal direction is about about 7.2 mm, the dimension of a transversal direction is about about 5.6 mm, and thickness is about about 0.4-0.6 mm.

  Further, as shown in FIGS. 5C and 6, the thin film portion 35 is integrally formed with a protruding portion 36 for suppressing vibration and preventing howling. Due to the presence of the protrusions 36, the reverberation of the vibration of the thin film portion 35 due to the user's voice is suppressed, and the voice is less likely to be trapped inside the waterproof case 21, so that the effect of preventing the howling phenomenon can be prevented. is there.

  In addition, as an example of the dimension of the protrusion part 36, the dimension of a longitudinal direction is about about 4 mm, the dimension of a transversal direction is about 1.8 mm, and height is about about 1-1.2 mm.

  The front side case member 24 is formed of a synthetic resin having rigidity, and a plate-like member 37 is provided at a position corresponding to the liquid crystal touch panel 25 provided on the front surface 22 e of the portable electronic device 22. The plate-like member 37 is formed of a transparent synthetic resin material that can see through information displayed on the liquid crystal touch panel 25, such as a polycarbonate resin.

  On the lower side of the plate-shaped member 37, an elastic home button pressing portion 39 is formed at a position corresponding to the home button 38 on the front surface 22 e of the portable electronic device 22.

  As shown in FIGS. 5A and 5B, the lower portion 40 of the front case member 24 has a hole 41 formed at a position corresponding to the thin film portion 35. Accordingly, since the thin film portion 35 of the back side case member 23 communicates with the outside without being obstructed by the lower portion 40 of the front side case member 24, the microphone portion (speaking mouth) 34a of the portable electronic device 22 is used by the user. Can be picked up clearly.

  The waterproof case 21 configured as described above is provided with a thin film portion 35 in which a silicone resin is formed in a thin film shape at the lower portion 33 of the back side case member 23, so that the microphone (speaking mouthpiece) of the portable electronic device 22 is provided. 34a can pick up the user's voice clearly.

  Furthermore, since the protrusion 36 for suppressing vibration and preventing howling is integrally formed on the thin film portion 35, the reverberation of the vibration of the thin film portion 35 due to the voice of the user is suppressed, so that the sound is It becomes difficult to clog up inside the waterproof case 21, and as a result, a howling phenomenon can be prevented.
